I am a 51 yo who has never smoked and has vigilantly avoided second-hand smoke because of lifelong hypersensitive lungs, mild asthma, frequent bronchitis when younger, and close family history of nonsmokers getting lung cancer and brochiectasis. (Lost a nonsmoking parent to lung cancer, others have had lung cancer too). After a bout with moderate COVID (after vax and boosters) that led to months of coughing and SOB, my dr ran tests, and high d-dimer caused her to do a lung CT to check for a pulmonary embolism. No PE but the scan showed mild centrilobular emphysema. I was shocked because of my almost nonexistent exposure to smoke. PFT was normal. I’m on Symbicort and still occasionally get SOB. I do not have alpha-1. Is it possible for the emphysema finding to be a mistake or a benign finding that may never meaningfully progress? Other than the hypersensitive lungs and the family history of other lung diseases I have no major risk factors for emphysema.
